I managed to misplaced the document that detailed the pin assignments in the wing root connector, so I spent a couple hours re-docmenting the assignments. The one that wasn't mounted was pretty easy. But the other one took over an hour to mount, so I didn't want to uninstall the connector. It was a little problematic, but I got it done.
I seem to have misplaced some pins for the wing root connectors, so I need to order some more.
I did wire one of the audio panel connectors. I'm going to use a DB-37 so that I can take the arm rest off during an inspection.
